G'Day Colonel,
It sounds like you may have one of two problems which can be diagnosed by the magnitude of the pyrotechnics generated. If you're getting an arc welder type of reaction when you put juice onto the contact, then I'd say you have a short inside the starter caused either by pinching one of the brush wires on assembly, (common problem) or one of the field coil cross over links may be touching on one of the through bolts. If it's a weeny little spark akin to the sort produced by a Zippo, then the cause could be a brush not contacting the commutator or a really poor connection between the chassis ground & the engine. Pop the cover band off the back of the starter & check the brushes & try connecting your ground terminal directly onto the engine somewhere. If that doesn't work you're going to have to re-live the rebuild procedure.

OutOfAfrica A's
: It seems the closer I get to cranking up my "A" after overhauling both the engine, transmission, and anything else that I saw move, the farther away I find myself from ignition!
: When I overhauled the starter a couple of months back, I thought it was a piece of cake (at least for an English Literature major).All I did was turn the commutator and replace the bushings.The brushes were okay, although there was some minor fraying on one or two of the wires in isolated spots.The shaft turns ever so smoothly to boot.
: Naturally, when I went to crank the engine for the "big test," nothing!I knew it had to be the starter switch -- it could not have been my rebuild.Wrong!Switch is fine, but putting juice to the starter terminal creates sparks, but nothing else.I should note that the starter worked perfectly prior to my overhaul.(I hate to admit that.)
: Are there continuity/voltage tests that I can perform to determine if there is a short (somewhat obvious), and where.Can one isolate whether the fault lies in the wiring to the brushes (they are seating well on the commutator), the windings on the armature, or the field coils?
: One day...
: Thanks in advance for any and all thoughts, polite or otherwise.
: Regards,
: Gordon
